I'm my case:Chromecast with Google TV (4K)Tried the usual steps,
Chromecast kept disconnecting. Only Chromecast disconnects, not the
other devices.5 GHz WiFi, 160MHz. 4 to 10 devices connected. Ubiquity
Unifi U6 Pro. No config change or updates recen...
It seems that the disconnections happens because my WiFi uses 160MHz
wide channels. It doesn't seem to disconnect if I use 80MHz.So for now
this seems to be a "fix", but it's definitely a new problem as it used
to be okay before.
